Distributed Primal-dual Optimization for Heterogeneous Multi-agent Systems

Yichuan Li, Petros Voulgaris, Nikolaos M. Freris

摘要:

异构网络包括在计算、存储和通信方面具有不同能力的代理。在这样的设置中,它是至关重要的因素,在允许代理选择适当的更新方案的操作特性,以便更好地分配计算任务,更有效地利用网络。考虑多智能体协作极小化局部强凸目标和的最优化问题。我们提出了一个异步分布式原始对偶协议,它允许原始更新步骤是代理依赖的(代理可以选择一阶或牛顿更新)。我们的分析引入了一个统一的框架,这种混合优化方案,并建立了全局线性收敛的期望,强凸目标和一般代理激活计划。在真实数据集上的数值实验证明了该算法的优越性。

英文摘要:

Heterogeneous networks comprise agents with varying capabilities in terms of computation, storage, and communication. In such settings, it is crucial to factor in the operating characteristics in allowing agents to choose appropriate updating schemes, so as to better distribute computational tasks and utilize the network more efficiently. We consider the multi-agent optimization problem of cooperatively minimizing the sum of local strongly convex objectives. We propose an asynchronous distributed primal-dual protocol, which allows for the primal update steps to be agent-dependent (an agent can opt between first-order or Newton updates). Our analysis introduces a unifying framework for such hybrid optimization scheme and establishes global linear convergence in expectation, under strongly convex objectives and general agent activation schemes. Numerical experiments on real life datasets attest to the merits of the proposed algorithm.
